Today I was going to spray epoxy primer on the 62 dodge. Soon as I started I noticed that the paint was sputtering from the gun leaving gaps with no paint. So then removed the paint container and the air ran smoothly from the gun. Reinstalled the tank and still had paint sputter. I then tried just spraying thinner thru the gun but got the same results. Took the spray gun totally apart and cleaned it all. Could not find anything wrong, it all looked spotless.
Would anyone have any idea what would cause this? This is a suction type gun made by Defillbus. Not sure of the spelling on that. Do have good clean dry air.
Any ideas?
I went to get my 300 dollar other sprayer, the one thats gravity fed, hvlp only to find that is no where in my possesion! No idea how long its been missing. Dam thieves.

Thanks, Alex
